Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997160, here are decompositions:

  • 7 + 997153 = 997160
  • 13 + 997147 = 997160
  • 19 + 997141 = 997160
  • 37 + 997123 = 997160
  • 61 + 997099 = 997160
  • 79 + 997081 = 997160
  • 103 + 997057 = 997160
  • 139 + 997021 = 997160

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 997,160 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
